Kōryū (コウリュウ): A master of Hokuto Shinken who once trained alongside Ryuken, his old rival, but yielded succession to avoid the tragic fate of Isshi Sōden. Koryu is also known as the 'Hokuto Tiger', while Ryuken was called the 'Hokuto Dragon'.

To prevent passing down his knowledge, he retreated to the mountains and led an ascetic life. However, Raoh seeks him out as his comeback opponent after his first fight with Kenshiro. Koryu fights reluctantly and tries to seal Raoh's fearsome power with a suicide attack called the Shichisei Massatsu (Seven Star Obliteration). Raoh breaks Koryu's hands off with a single punch and pummels him to death.

After the fight, Raoh meets Koryu's two sons, Zeus and Aus, and spares their lives after they attempt to avenge their father. As a parting gift, he tells them to choose different paths or face the same fate, a foreshadowing to his impending battle with Toki. In the manga, Zengyo (Koryu's servant) brings news of his master's death to Kenshiro and Toki.
